Abstract: Embodiments provided herein allow for identification of one or more regions of interest in a radar return signal that would be suitable for selected application of super-resolution processing. One or more super-resolution processing techniques can be applied to the identified regions of interest. The selective application of super-resolution processing techniques can reduce processing requirements and overall system delay. The output data of the super-resolution processing can be provided to a mobile computer system. The output data of the super-resolution processing can also be used to reconfigure the radar radio frequency front end to beam form the radar signal in region of the detected objects. The mobile computer system can use the output data for implementation of deep learning techniques. The deep learning techniques enable the vehicle to identify and classify detected objects for use in automated driving processes. The super-resolution processing techniques can be implemented in analog and/or digital circuitry.

Abstract: Methods, systems, computer-readable media, and apparatuses for determining one or more attributes of at least one target based on eigenspace analysis of radar signals are presented. In some embodiments, a subset of eigenvectors to use for forming a signal or noise subspace is identified based on principal component analysis. In some embodiments, the subset of eigenvectors is identified based on estimating the total number of targets using a discrete Fourier transform (DFT) or other spectral analysis technique. In some embodiments, a DFT is used to identify areas of interest in which to perform eigenspace analysis. In some embodiments, a DFT is used to estimate one attribute of a target, and eigenspace analysis is performed to estimate a different attribute of the target, with the results being combined to generate a multi-dimensional representation of a field of view.

Abstract: An example LIDAR system includes a detector, an amplifier, a time-to-digital converter (TDC), an integrator, an analog-to-digital converter (ADC), and a processor. The detector is configured to receive a reflected light pulse, where the reflected light pulse is reflected off of an object. The amplifier is coupled to the detector to generate an analog signal in response to the reflected light pulse. The TDC is coupled to the amplifier to generate a first time data and a second time data in response to the analog signal. The integrator is coupled to the amplifier to integrate the analog signal. The ADC is coupled to the integrator to sample an output of the integrator and to generate a digital sample. The processor is configured to process the first time data, the second time data, and the digital sample to estimate a total reflected energy of the reflected light pulse.

Abstract: An electronic imaging device and method for image capture are described. The imaging device includes a camera configured to obtain image information of a scene and that may be focused on a region of interest in the scene. The imaging device also includes a LIDAR unit configured to obtain depth information of at least a portion of the scene at specified scan locations of the scene. The imaging device is configured to detect an object in the scene and provides specified scan locations to the LIDAR unit. The camera is configured to capture an image with an adjusted focus based on depth information, obtained by the LIDAR unit, associated with the detected object.

Abstract: Methods, systems, and devices for wireless communications are described. A vehicle-based wireless device may receive a calibration availability message from a roadside unit identifying one or more calibration characteristics of a calibration object associated with the roadside unit. The vehicle-based wireless device may determine one or more sensor characteristics for a sensor of the vehicle and the vehicle. The vehicle-based wireless device may measure the one or more calibration characteristics of the calibration object using the sensor while the vehicle is within a defined range of the calibration object. The vehicle-based wireless device may perform a calibration procedure to calibrate the sensor based at least in part on the identified one or more calibration characteristics, the measured one or more calibration characteristics, and the one or more sensor characteristics.

Abstract: Methods, systems, computer-readable media, and apparatuses for outputting light are presented. A method includes outputting, via a propagation wave source and toward a field of view (FOV), at least one propagated wave at a first power, receiving, via a sensor, a reflection of the at least one propagated wave at the first power reflected off one or more objects within the FOV, classifying, via a processor, one or more areas within the FOV into safe areas and unsafe areas based at least in part on the received reflection of the propagated wave at the first power, wherein the safe areas are deemed to be safe to receive at least one propagated wave at a second power, and outputting, via the propagation wave source and toward the safe area, the at least one propagated wave at the second power. The first power may be a lower power than the second power.

Abstract: Techniques for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle can include monitoring the primary mode of RF communication to ensure it is effectively communicating and, if not, intelligently selecting a backup communication mode comprising one or more other sensors and/or systems of the vehicle. The selection of the backup communication mode may take into account various factors that can affect the various modes of communication from which the backup communication mode is selected.

Abstract: Methods and apparatus for providing dynamically adjusted radiated signals are disclosed. In one aspect, a method of detecting one or more objects in a path of travel of a vehicle may include generating a laser with radiated power. The method may further include emitting the laser in a direction of travel of the vehicle and receiving one or more reflections of the emitted laser reflected from the one or more objects located in the direction of travel of the vehicle. The method may also further include generating a signal indicating that the one or more objects are in a path of the vehicle based on the received one or more reflections. The method may also include dynamically adjusting the radiated power of the laser based on an input corresponding to one or more of (i) a current speed of the vehicle or (ii) a current position of the vehicle.
